Key result
Compared to radiography, hip ultrasonography demonstrated a sensitivity of 45.7% (95% CI 41.5-45.7) and specificity of 100% for detecting abnormal hip development in treated DDH.
Why the study?
The study aimed to compare radiographic and ultrasonographic findings in patients treated for developmental dysplasia of the hip.
Does hip ultrasonography accurately detect abnormal hip development compared to radiography in infants treated for DDH?
Observational (n=88)
Does hip ultrasonography accurately detect abnormal hip development compared to radiography in infants treated for DDH?
Effect estimate: Sensitivity 45.7% (95% CI 41.5-45.7)
Hip maturation apparent on ultrasonography may not be consistent with radiographic hip development in infants treated for DDH, demonstrating low sensitivity compared to radiography.
No takes yet. Share an insight, caveat, or question.
Hip ultrasonography's low sensitivity cautions against sole use for DDH monitoring; leaves open need for prospective imaging validation studies.
Atalar et al. (2019) conducted an observational in Developmental dysplasia of the hip (DDH) (n=88). Hip ultrasonography vs. Radiography was evaluated on Detection of abnormal hip development (Sensitivity 45.7%, 95% CI 41.5-45.7). Compared to radiography, hip ultrasonography demonstrated a sensitivity of 45.7% (95% CI 41.5-45.7) and specificity of 100% for detecting abnormal hip development in treated DDH.
